A fastening tool with low noise, low vibration and low reaction force
Basic model of impulse wrench
What is an impulse wrench (oil pulse wrench)?
Compared to impact wrenches, which utilize the striking force of metal, a hydraulic chamber (liner case) is placed between the motor and shaft, and the oil inside is suddenly compressed, and the pressure is transmitted to the shaft to generate rotational torque, significantly reducing the noise and vibration generated by the tool.
Fastening torque (generated torque) adjustment Hydraulic pressure adjustment function
The generated torque can be adjusted by opening and closing the relief valve (adjustment bolt) inside the liner case.
- Developed with the aim of being compact and lightweight, this is the base model for Yokota impulse wrenches today.
